Detroit Tigers trio Jose Iglesias, Bruce Rondon and Luke Putkonen are all progressing well, with Putkonen still a candidate to return before the end of the season. MLB.com's Jason Beck writes that the reliever, who is recovering from right elbow inflammation, threw off a mound for the first time and is aiming to be back in the Tigers bullpen before the end of September. Meanwhile, James Schmehl of MLive.com reports that Iglesias has started lower body conditioning work as he endeavours to come back to stress fractures in both shins. Schmehl also says that Rondon is close to playing catch after his Tommy John surgery in March, but Joel Hanrahan is not doing as well, with no sign that he will be able to pitch at all this season after his most recent setback.
